FAQs on Viscosity and Poiseuille's Law Video Lecture - Basic Physics for IIT JAM
| 1. What is viscosity and how is it related to Poiseuille's Law? |  |
Ans. Viscosity refers to the measure of a fluid's resistance to flow. It determines how easily a fluid can flow when a force is applied to it. Poiseuille's Law, on the other hand, relates the flow rate of a fluid through a cylindrical pipe to the viscosity of the fluid, the pressure difference across the pipe, and the dimensions of the pipe.
| 2. How is viscosity measured? | |
Ans. Viscosity is typically measured using a viscometer. The most common type of viscometer is the rotational viscometer, where a spindle is rotated at a constant speed in the fluid. The resistance to rotation is then measured, and the viscosity is calculated based on the applied torque and the dimensions of the viscometer.
| 3. What factors affect the viscosity of a fluid? | |
Ans. The viscosity of a fluid is influenced by several factors, including temperature, pressure, and the presence of additives or impurities. Generally, as temperature increases, the viscosity of most fluids decreases. Higher pressures tend to increase viscosity. Additionally, the presence of additives or impurities can alter the viscosity of a fluid.
| 4. How does Poiseuille's Law explain the flow of fluids through pipes? | |
Ans. Poiseuille's Law states that the flow rate of a fluid through a cylindrical pipe is directly proportional to the pressure difference across the pipe and the fourth power of the radius of the pipe, and inversely proportional to the viscosity of the fluid and the length of the pipe. It mathematically describes the relationship between these variables and provides a quantitative understanding of fluid flow in pipes.
| 5. Can Poiseuille's Law be applied to fluids with non-Newtonian behavior? | |
Ans. Poiseuille's Law assumes that the fluid being analyzed exhibits Newtonian behavior, meaning that its viscosity remains constant regardless of the applied shear stress. However, for fluids with non-Newtonian behavior, such as those with varying viscosities under different shear conditions, Poiseuille's Law may not accurately predict their flow rates. In such cases, alternative models or empirical relationships specific to the non-Newtonian fluid behavior should be considered.
